Atheist Prejudices?

A small thought as to my own prejudices got me to wondering if these are linked to my atheist position. I know a lot of us have a prejudice based mainly on theists and this can range from mild irritation to outright hatred. This is one of my own prejudices, for as soon as I discover a person's religious beliefs (or the strength of their religious beliefs to be more accurate) I tend to label them with an equivalent intelligence level, even though I know rationally that this is not always the case for I have met intelligent theists and they do exist. I know I tend to think this because I equate atheism with rationality and logic which I know all of us do.

I wondered if there are any other typical atheists prejudices that you think we may have? Or perhaps any prejudices that you yourself may have that you have noticed?

Any typical prejudices that we may be strictly against, such as theists 'satanistic' assumptions about us?
